According to this article nine out of ten food allergy cases are all in the mind. Researchers say that nine out of ten Britons who believe they have a food allergy or intolerance are actually perfectly healthy. Studies show that although 20 per cent of adults claim they cannot eat certain foods when in reality fewer than 2% actually have a problem. Internet searches, self testing kits and celebrity food fads are blamed for the problem which causes millions of people to restrict their diet unnecessarily. Other people could be suffering from a medical problem which goes untreated because they believe they are suffering a food intolerance instead. The advice here is to see your doctor to receive a correct diagnosis.
